They are incredibly versatile, fitting nearly every standard longboard, single fin, or SUP box on the market. Just keep in mind that if you ride a Starboard or Naish paddleboard, these might be a bit too short for your specific setup. It is a small price to pay for a reliable, tool-free solution that comes in a convenient three-pack.

Because these are made of real stainless steel, you don't have to worry about the rapid corrosion that typically plagues cheaper hardware after a few salty sessions.
